Message quote:

What are the differences between short tubes and long tubes?
The longer the tube the greater the pressure loss accompanied by a slight increase in efficiency.

Does the length of the tube affect efficiency?
Very little. The most heat comes out of the tube where the temperature difference between the inside and the outside is the greatest. That exists in the first couple inches of the tube. The last inch of the tube, wherein the charge temperature is rapidly approaching the cooling media temperature, will transfer very little heat, thus being of minor use.
